- Naming classes and methods correctly is crucial as it influences code structure, future thinking, refactoring, and extension, with poor naming leading to technical debt.
- Using '-er' suffixes like 'Manager' often indicates poor design; for example, 'ConnectionManager' became complex with multiple responsibilities, whereas 'Connection' would have been clearer and simpler.
- Choosing precise names helps maintain clean code, simplifies extension and refactoring, and reduces complexity and bugs, so spending extra time on naming is recommended.
